Application filed July 3,

My invention relates to a dish washing for its purpo e to adord a simpleand practicable mechanism that can be readily and economicallymanufactured, and lends itself to use in restaurants and hotels, withconsiderable facility and etficiency.

A more particular object oi the invention is to afford a structure inwhich the dishes are stationary, and the water is brought into contacttherewith violently and continuously. maximum agitation of the waterbeing ore atedto bring about a quick and thorough cleansing action.

With these and other ends in view, the invention comprises the structurethat will appearclearly from the following. description, when read inconjunction with the accompanying drawings, the novel features being:pointed out in the claims following the detailed description.

In the drawings:

Figure 1 is a side view of a dishwashing machine incorporating oneembodiment oi the invention:

Figure 2 is a longitudinal vertical sectional view;

Fiqure 3 is a plan View;

Figure 4 is ahorizontal sectional View on line H of Figure 2;

Figure 5 is a transverse vertical sectional view showing one position ofthe water displacer, the arrows indicating the flow of water produced bythe displacer;

Figure 6 is a similar view with the water displacer in its oppositeposition, and the arrows indicating the corresponding reverse movementof the water; i 1

Figure 7 is a perspective view of the water displacer, and

Figure 8 is a displacer.

In the construction disclosed. which is understood to be merelyillustrative of one practical embodiment of the invention, 1 designatesa water receptacle, while 2 is a dish support upon which the loaded dishbasket 3 may be positioned in the usual manner in this class ofmachinery.

The water is agitated inthe receptacle and forced through the dishbasket by a displacer, so constructed as to displace a substantialvolume of water. As the displacer travels'it'rom one part of thereceptacle to another, it houses and moves with it a substantial volumeof water and an equal sectional view ot the water 1924. Serial No.723,991).

amount of water is constantly rushing. in behind to occupy the spacepreviou' ly filled by the displacer, which at the same time is drivingwater ahead of it. In this way, a very thorough and powerful agitationis created and good results are obtained by moving the displacer ha kand torth beneath the dish support. Preferably the volume of water sodisplaced is ubstantially equal to the volume between the bottom of thedish support and the bottom of the water container and which the latterhouses and moves along. A the d snlacer travel bac z and forth under thedishes. a considerable body of water i sucked in behind the displacerand a corresponding; volume of water is forced in trout ot the displacerupwardly through the dish baskehas indicated by the arrows in Figures 5and 6. To accomplish this. the dish support 2 is located in spacedrelation above the bottom 4 of the water receptacle, aiiordinp; a spaceunderneath the dish support to permit movement of the water displacerthat will now be described.

The water displacer may be constructed and have amovement other thanthat specifically disclosed. but in its preferred form, comprises abottomless hou ing; having a top wall 5. front wall 6. and side walls 7.The side walls 7 are inclined downwardly, as shown in Figures 2, and 7,so as to reduce the resi tance to the back and forth travel of the waterdisplacer. lhe displacer having no bottom, itsinterior is filled withwater which moves back and forth therewith. Thus the displacer has notendency to float, and the omission'ot the bottom renders itcomparatively light, resulting: in an easier operation. At its rear, thedisplacer is provided with an upwardly extending deflecting portionincluding a central wall 8 and side walls 9. the latterheing inclinedrearwardly. This deflecting portion is located to one side of thedishsupport and dish. basket and travels along the side thereof, tendingto ooncen trate the water more or less toward the center of the waterreceptacle and direct it with greater eli'ect through the dish basket.10 designates guide rods arranged longitudinally oi the water receptaclebeneath the dish support, and adapted to receive the displacer which isslidable back and forth thereon. In order to further assist the displacer in its movement and reduce the amount of power required operatingthe more; with considerable violence machine, a float or air chaniberll"may be secured to the displacer underneath the top thereof, as shown inFigure 8. The displacer may be operated in any snitabloway either byhandor motor power, and as a possible means oi. accomplishment, I' haveillustrated an operating. lever 12p1v0ted at 13 and connected by thelink 14 to the vertical wall 8 of the displacer-r V l The. machine beingproperly filled-A wlth water; a, basket loaded with ,dishesqis placedon" the dish snpport'fl and; the lever 12: is then oscillated,- causingthewater. displacerimthe bottom of thecontainer to-recip rocate beneaththe dish supper The water'displacer confines a substantial volume ofwater,L-mov;ing the same baclo and fOIlihyiLt the same:time causing;thewater int-the re ceptacle in advance of the: displaces to upwardlyand laterally through-tho dishibasket, first in lonevdirection and then:in the other, while the Waterbehind: the displacer is, rushing towardit to fill the VOlCl" created by movement ofthe displacer.
